Robo-graders as good as human standardized essay test graders, claims a recent study. (Who paid for the study?) Yet tests done by an independent skeptic show the robo-grader can be easily gamed with random, incorrect facts and wordy writing.
A great excerpt from the article:
"Two of the biggest for-profit education companies, Vantage Learning and Pearson, turned down my request to let Mr. Perelman test their products.
'He wants to show why it doesn’t work,' said Peter Foltz, a Pearson vice president.
'Yes, I’m a skeptic,' Mr. Perelman said. 'That’s exactly why I should be given access.'”
